Javascript change value when choose on select box

Question

<center>
<div class="main">
  <div class="harga">Rp.2,680,000 / Bln</div>
  <div class="other">Kontrak Setahun
  atau <label>Rp. 2,930,000 / Bln</label></div>
  </br>
  <div class="traffic">Pilih traffic Anda dibawah ini</div>
  <select class="visitor">
    <option value="5,000">Up To 5,000</option>
    <option value="7,900">Up To 7,900</option>
    <option value="17,600">Up To 17,600</option>
    <option value="25,000">Up To 25,000</option>
  </select>
  </br>
  Visitor / Bulan
</div>
</center>

<script type="text/javascript">
  $(function() {
    if((".visitor").val() == "5,000") {
      $(".harga").value == "4000";
    }
  });
</script>

i have this script, how can I change the value on harga from visitor, when I choose selection from select box?

Add a .change() handler to the select, and put your if inside the handler? — nnnnnn

Not directly helpful to your question, but consider losing the <center> tag in favor of CSS positioning on div.main. Also, try <br /> rather than </br>. — SimianAngel

Also, are you meaning to update the text of div.harga? Because attempting to manipulate the .value property is not gonna work, because value isn't a property of the jQuery object you return in your script. You could use .text(), or else .harga needs to belong to an form element of some sort. And if you meant to have that be an input element, then you need to either use jQuery's .val() method to set it, or get that specific DOM node from the jQuery object, which then has a value property. — SimianAngel

Use change event like this

$('.visitor').change(function(){
        if($(this).val()  == '5,000'){
                // write your to do action here
        }
});
